Good old Unix.mktime could perhaps do the job.  It has the ability to
correct for impossible dates, e.g. change Sept 32nd into Oct 2nd,
or 2003-13-01 into 2004-01-01.

So, perhaps you could just increment the tm_mday, tm_mon or tm_year of
a "tm" record by the specified amount, then call Unix.mktime and
discard the first result to get a normalized, but equivalent date.
